ReviewHysteroscopic tubal sterilization: a health economic literature review.
Hysteroscopic sterilization is a minimally invasive alternative to laparoscopic tubal ligation for women who want permanent contraception. In contrast to the laparoscopic technique, a hysteroscope is used to pass permanent microinserts through the cervix and place them in the fallopian tubes. This procedure does not require local or general anesthesia and can be performed in an office setting. ⋯ Hysteroscopic sterilization is a minimally invasive alternative to conventional tubal ligation for women who want a permanent method of contraception. Both approaches involve closing off the fallopian tubes, preventing the egg from moving down the tube and the sperm from reaching the egg. Tubal ligation is a surgical procedure to tie or seal the fallopian tubes, and it usually requires general anesthesia. In contrast, hysteroscopic tubal sterilization can be performed in 10 minutes in an office setting without general or even local anesthesia. A tiny device called a microinsert is inserted into each fallopian tube through the vagina, cervix, and uterus without surgery. An instrument called a hysteroscope allows the doctor to see inside the body for the procedure. Once the microinserts are in place, scar tissue forms around them and blocks the fallopian tubes. Health Quality Ontario commissioned a systematic review of published economic literature to determine whether hysteroscopic sterilization is cost-effective compared to tubal ligation. This review did not find any studies that reported results in terms of both costs and effectiveness or costs and quality-adjusted life-years. We did find 3 costing studies and included them in our review. All of these studies found that when hysteroscopic sterilization was performed as an outpatient procedure, it was less expensive than tubal ligation due to a shorter recovery time. However, none of the studies apply directly to Ontario because of differences in our health care system compared to those in the studies.

Review Meta AnalysisChronic disease patients' experiences with accessing health care in rural and remote areas: a systematic review and qualitative meta-synthesis.
Rurality can contribute to the vulnerability of people with chronic diseases. Qualitative research can identify a wide range of health care access issues faced by patients living in a remote or rural setting. ⋯ People who live in a rural area may feel more vulnerable--that is, more easily harmed by their health problems or experiences with the health care system. Qualitative research looks at these experiences from the patient's point of view. We found 3 broad concerns in the studies we looked at. The first was geography: needing to travel long distances for health care can make care hard to reach, especially if transportation is difficult or the weather is bad. The second concern was availability of health professionals: rural areas often lack health care services. Patients may also feel powerless in "referral games" between rural and urban providers. People with low education or without others to help them may find navigating care more difficult. When rural services are available, patients like seeing clinicians who have known them for a long time, and like how familiar clinicians treat them as a whole person. The third concern was rural culture: patients may feel like outsiders in city hospitals or clinics. As well, in rural communities, people may share a feeling of self-reliance and community belonging. This may make them more eager to take care of themselves and each other, and less willing to seek distant care. Each of these factors can increase or decrease patient vulnerability, depending on how health services are provided.

Review Meta AnalysisElectrical stimulation for drug-resistant epilepsy: an evidence-based analysis.
The objective of this analysis was to evaluate the effectiveness of deep brain stimulation (DBS) and vagus nerve stimulation (VNS) for the treatment of drug-resistant epilepsy in adults and children. ⋯ Electrical stimulation of specific areas of the brain is a procedure used to control epileptic seizures when more conventional treatments are not working. Most adults and children with epilepsy are able to control their seizures with medication, but for some patients, drugs are not effective and surgery to remove the part of the brain where the seizures start is not an appropriate option. This study looked at the research available on the effectiveness, safety, and cost of two types of electrical stimulation devices currently licensed for treatment of epilepsy for adults and children in Canada: vagus nerve stimulation (VNS) and deep brain stimulation (DBS). Both approaches appear to be effective at reducing the frequency of seizures in adults. However, the evidence on DBS is limited to a single study with adults; we found no studies of DBS with children. Studies on VNS showed that both adults and children had fewer hospitalizations and emergency department visits after the procedure. Both procedures carry serious risks, but several longer-term studies have found that adverse events appear to be limited. The cost of VNS, including the process of assessing whether or not patients are good candidates for the procedure, is estimated to be about $40,000 per person (and higher for DBS because the device is more expensive and the operating time is longer). Of the 70,000 people in Ontario with epilepsy, about 1,400 (300 children and 1,110 adults) may be candidates for VNS to reduce their seizures.

Review Meta AnalysisElectronic tools for health information exchange: an evidence-based analysis.
As patients experience transitions in care, there is a need to share information between care providers in an accurate and timely manner. With the push towards electronic medical records and other electronic tools (eTools) (and away from paper-based health records) for health information exchange, there remains uncertainty around the impact of eTools as a form of communication. ⋯ Patients with chronic diseases often work with many different health care providers. To ensure smooth transitions from one setting to the next, health care providers must share information and coordinate care effectively. Electronic medical records (eTools) are being used more and more to coordinate patient care, but it is not yet known whether they are more effective than paper-based health records. In this analysis, we reviewed the evidence for the use of eTools to exchange information and coordinate care for people with chronic diseases in the community. There was some evidence that eTools reduced the number of hospital and emergency department visits, as well as patients' length of stay in the hospital, but there was no evidence that eTools improved the overall quality of patient care.

Review Meta AnalysisExperiences of patient-centredness with specialized community-based care: a systematic review and qualitative meta-synthesis.
Specialized community-based care (SCBC) endeavours to help patients manage chronic diseases by formalizing the link between primary care providers and other community providers with specialized training. Many types of health care providers and community-based programs are employed in SCBC. Patient-centred care focuses on patients' psychosocial experience of health and illness to ensure that patients' care plans are modelled on their individual values, preferences, spirituality, and expressed needs. ⋯ More and more, to reduce bed shortages in hospitals, health care systems are providing programs called specialized community-based care (SCBC) to patients with chronic diseases. These SCBC programs allow patients with chronic diseases to be managed in the community by linking their family physicians with other community-based health care providers who have specialized training. This report looks at the experiences of patients and health care providers who take part in SCBC programs, focusing on psychological and social factors. This kind of lens is called patient-centred. Three themes came up in our analysis: patients' health beliefs affect how they take part in SCBC interventions; patients' experiences with care in the community differ from their experiences with care in the hospital; patients and providers value the role of nurses differently. The results of this analysis could help those who provide SCBC programs to better meet patients' needs.
