Strategies for integrating primary health services in middle- and low-income countries at the point of delivery.

Cochrane Database Syst Rev. 2006;(2):CD003318

Authors: Briggs CJ, Garner P

BACKGROUND: Strategies to integrate primary health care aim to bring together inputs, organisation, management and delivery of particular service functions to make them more efficient, and accessible to the service user. In some middle and low income countries, services have been fragmented by separate vertical programmes established to ensure delivery of particular technologies. We examined the effectiveness of integration strategies at the point of delivery. OBJECTIVES: To assess the effects of strategies to integrate primary health care services on producing a more coherent product and improving health care delivery and health status. SEARCH STRATEGY: We searched the Cochrane Effective Practice and Organisation of Care Group specialised register (August 2005), MEDLINE (1966 to September 2005), EMBASE (1988 to 2005), Socio Files (1974 to September 2005), Popline (1970 to September 2005), HealthStar (1975 to September 2005), Cinahl (1982 to September 2005); Cab Health (1972 to 1999), International Bibliography of the Social Sciences (1970 to 1999), and reference lists of articles. We also searched the Internet and World Health Organization (WHO) library database, hand searched relevant WHO publications and contacted experts in the field. SELECTION CRITERIA: Randomised trials, controlled before and after studies, and interrupted time series analyses of integration strategies in primary health care services. Health services in high-income countries were excluded. The primary outcomes were indicators of health care delivery, user views on any measure of service coherence, and health status. We also sought information on comparative costs. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data and assessed study quality. MAIN RESULTS: Three cluster randomised trials and two controlled before and after studies were included, with three types of comparison: integration by adding on an additional component to an existing service (family planning); integrated services versus single special services (for sex workers); integrated delivery systems versus a vertical service (for family planning); and packages of enhanced primary child care services (integrated management of childhood illnesses) vs. routine child care. Interventions were complex and in some studies inputs varied substantially between comparison arms. Overall, no consistent pattern emerged. Only one study attempted to assess the user's view of the service provided. AUTHORS' CONCLUSIONS: Few studies of good quality, large and with rigorous study design have been carried out to investigate strategies to promote service integration in low and middle income countries. All describe the service supply side, and none examine or measure aspects of the demand side. Future studies must also assess the client's view, as this will influence uptake of integration strategies and their effectiveness on community health.

Percutaneous needle aspiration, injection, and reaspiration with or without benzimidazole coverage for uncomplicated hepatic hydatid cysts.

Cochrane Database Syst Rev. 2006;(2):CD003623

Authors: Nasseri Moghaddam S, Abrishami A, Malekzadeh R

BACKGROUND: Hepatic hydatid cyst is an important public health problem in parts of the world where dogs are used for cattle breeding. Management of uncomplicated hepatic hydatid cysts is currently surgical. However, the puncture, aspiration, injection, and re-aspiration (PAIR) method with or without benzimidazole coverage has appeared as an alternative to surgery over the past decade. OBJECTIVES: To assess the benefits and harms of PAIR with or without benzimidazole coverage for patients with uncomplicated hepatic hydatid cyst in comparison with sham/no intervention, surgery, or medical treatment. SEARCH STRATEGY: The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Controlled Trials Register in The Cochrane Library, MEDLINE, EMBASE, DARE, and ACP Journal Club and full text searches were combined (all searched October 2004). Reference lists of pertinent studies and other identified literature were scanned. Researchers in the field were contacted. SELECTION CRITERIA: Only randomised clinical trials using the PAIR method with or without benzimidazole coverage as the experimental treatment of uncomplicated hepatic hydatid cyst (ie, hepatic hydatid cysts which are not infected and do not have any communication with the biliary tree or other viscera) versus no intervention, sham puncture (ie, performing all steps for puncture, pretending that PAIR is being performed, but actually not performing the procedure proper), surgery, or chemotherapy were included. DATA COLLECTION AND ANALYSIS: Data were independently extracted and methodological quality of each trial was assessed by the authors. Principal authors of the trials were contacted to retrieve missing data. MAIN RESULTS: We found no randomised clinical trials comparing PAIR versus no or sham intervention. We identified only two randomised clinical trials, one comparing PAIR versus surgical treatment (n = 50) and the other comparing PAIR (with or without albendazole) versus albendazole alone (n = 30). Both trials were graded as 'adequate' for allocation concealment; however, generation of allocation sequence and blinding methods were 'unclear' in both of them. Compared to surgery, PAIR plus albendazole obtain similar cyst disappearance and mean cyst diameter with fewer adverse events (32% versus 84%, P < 0.001) and fewer days in hospital (mean + SD) ( 4.2 + 1.5 versus 12.7 + 6.5 days, P < 0.001). Compared to albendazole, PAIR with or without albendazole obtain significantly more often (P < 0.01) cyst reduction and symptomatic relief. AUTHORS' CONCLUSIONS: PAIR seems promising, but there is insufficient evidence to support or refute PAIR with or without benzimidazole coverage for treating patients with uncomplicated hepatic hydatid cyst. Further well-designed randomised clinical trials are necessary to address the topic.

Clotting factor concentrates given to prevent bleeding and bleeding-related complications in people with hemophilia A or B.

Cochrane Database Syst Rev. 2006;(2):CD003429

Authors: Stobart K, Iorio A, Wu JK

BACKGROUND: People with severe hemophilia A or B, X-linked bleeding disorders due to decreased blood levels of coagulants, suffer recurrent bleeding into joints and soft tissues. Before clotting factor concentrates were available, most people with severe hemophilia developed crippling musculoskeletal deformities. Clotting factor concentrate prophylaxis aims to preserve joint function by converting severe hemophilia (factor VIII or IX less than 1%) into a clinically milder form of the disease. Prophylaxis has long been used in Sweden, but not universally adopted because of medical, psychosocial, and cost controversies. Use of clotting factor concentrates is the single largest predictor of cost in treating hemophilia. OBJECTIVES: To determine the effectiveness of clotting factor concentrate prophylaxis in the management of people with hemophilia A or B. SEARCH STRATEGY: We searched the Cystic Fibrosis and Genetic Disorders Group's Trials Register comprising references from comprehensive electronic database searches and handsearches of journals and abstract books. Reference lists of relevant articles were reviewed.Most recent search: November 2005. SELECTION CRITERIA: Randomized controlled trials (RCTs) evaluating people with severe hemophilia A or B, receiving prophylactic clotting factor concentrates. DATA COLLECTION AND ANALYSIS: Two authors independently reviewed studies for eligibility, assessed methodological quality and extracted data. MAIN RESULTS: Twenty-nine studies were identified; four studies (including 37 participants) were eligible for inclusion. Three studies evaluated hemophilia A; one showed a decrease in frequency of joint bleeds with prophylaxis compared to placebo (non-physiological dose), with a rate difference (RD) -10.80 (95% confidence interval (CI) -16.33 to -5.27) bleeds per year. The remaining two studies evaluating hemophilia A compared two prophylaxis regimens, one study showed no difference in joint bleed frequency, RD -5.04 (95%CI -17.02 to 6.94) bleeds per year and another failed to demonstrate an advantage of factor VIII dosing based on individual pharmacokinetic data over the standard prophylaxis regimen with RD -0.14 (95% CI -1.34 to 1.05) bleeds per year. The fourth study evaluated hemophilia B and showed fewer joint bleeds with weekly (15 IU/kg) versus bi-weekly (7.5 IU/kg) prophylaxis, RD -3.30 (95% CI -5.50 to - 1.10) bleeds per year. AUTHORS' CONCLUSIONS: There is insufficient evidence from randomised controlled trials to determine whether prophylactic clotting factor concentrates decrease bleeding and bleeding-related complications in hemophilia A or B, compared to placebo, on-demand treatment, or prophylaxis based on pharmacokinetic data from individuals. Well-designed RCTs are needed to assess the effectiveness of prophylactic clotting factor concentrates. Two clinical trials are ongoing.

Rest during pregnancy for preventing pre-eclampsia and its complications in women with normal blood pressure.

Cochrane Database Syst Rev. 2006;(2):CD005939

Authors: Meher S, Duley L

BACKGROUND: Women at risk of pre-eclampsia or gestational hypertension are sometimes advised to rest. Whether this, overall, does more good than harm is unclear. OBJECTIVES: To assess the effects of rest or advice to reduce physical activity during pregnancy for preventing pre-eclampsia and its complications in women with normal blood pressure. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group Trials Register (December 2005), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 3, 2005), and EMBASE (2002 to August 2005). SELECTION CRITERIA: Studies were included if they were randomised trials evaluating the effects of rest or advise to reduce physical activity for preventing pre-eclampsia and its complications in women with normal blood pressure. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials for inclusion and extracted data. Data were double checked for accuracy. MAIN RESULTS: Two small trials (106 women) of uncertain quality were included. Both recruited women with a singleton pregnancy at moderate risk of pre-eclampsia from 28 to 32 weeks' gestation. There was a statistically significant reduction in the relative risk of pre-eclampsia with four to six hours rest per day (one trial, 32 women; relative risk (RR) 0.05, 95% confidence interval (CI) 0.00 to 0.83), but not of gestational hypertension (RR 0.25, 95% CI 0.03 to 2.00), compared to normal activity. Rest of 30 minutes per day plus nutritional supplementation was associated with a reduction in the risk of pre-eclampsia (one trial, 74 women; RR 0.13, 95% CI 0.03 to 0.51) and also of gestational hypertension (RR 0.15, 95% CI 0.04 to 0.63). The effect on caesarean section was unclear (RR 0.82, 95% CI 0.48 to 1.41). No other outcomes were reported. AUTHORS' CONCLUSIONS: Daily rest, with or without nutrient supplementation, may reduce the risk of pre-eclampsia for women with normal blood pressure, although the reported effect may reflect bias and/or random error rather than a true effect. There is no information about outcomes such as perinatal mortality and morbidity, maternal morbidity, women's views, adverse effects, and costs. Current evidence is insufficient to support recommending rest or reduced activity to women for preventing pre-eclampsia and its complications. Whether women rest during pregnancy should therefore be a matter of personal choice.
